Description
Technical field
The invention belongs to material atmospheric corrosion studying technological domains, and in particular to one kind is used for austenite stainless steel workpiece table
The patch and its application method of surface treatment.
Background technique
The etching problem of metal material and its workpiece spreads the every field of national economy, and resulting loss accounts for about gold
Belong to 50% or more of year loss amount, and other than huge economic loss, it also will cause many catastrophic failures.Therefore to gold
Belong to material and its workpiece progress anti-corrosion protection processing is significant.
There are many kinds of existing anti-corrosion protection measures, and wherein passivation protection has very important status, and is passivated
Processing goes to contact to start the cleaning processing, and Seal treatment is also carried out after Passivation Treatment.
It industrially commonly uses passivator (mainly oxidant) and processing is passivated to metal, form layer protecting film.With
Traditional physical containment method is compared, and is had the characteristics that not increase thickness of workpiece after Passivation Treatment and is changed color, improves product
Precision and added value, make more convenient operation；Secondly, oxygen minor structure passivating film, film that passivation promotes metal surface to be formed
Layer is fine and close, performance is stablized, and has self-repair function simultaneously in air, therefore the method phase with traditional painting antirust oil
, more corrosion resistance more more stable than, the passivating film for being passivated formation.
For workpiece in practical Passivation Treatment, surface can be because there is the pollutant effects Passivation Treatment effect such as grease to need to carry out
Cleaning carries out acid wash passivation processing, carries out the post-processing such as closing after pickling, dissimilar metal is avoided to contact with nonmetallic after cleaning
Equal destructions are passivated protection effect.
In the industrial production, certain austenitic stainless steel materials or workpiece are in molding or after processing is completed, traditional chemistry
Processing technique is not able to satisfy the requirement of actual condition, for example, on the one hand establishing large-scale for the solder joint Passivation Treatment of larger workpiece
Treatment trough will greatly increase production cost, influence production efficiency, do not meet actual demand；On the other hand, because of related reagent
Mobility, it cannot be guaranteed that related reagent, which converges to, wants treatment site.
In view of this, the present invention is specifically proposed.
Summary of the invention
In order to overcome the above technical problems, the present invention propose it is a kind of for austenite workpiece surface processing patch and its make
Use method.It realizes by using the combination of three kinds of patches containing different disposal agent to large scale, special-shaped austenite workpiece
